The scale wall A computer vision pipeline that works on one image at one resolution isn't a pipeline. It's a prototype. The moment you move beyond controlled inputs, you hit the reality of production images: a 4K video frame, a satellite capture, a whole-slide pathology image, a high-resolution document scan. These images don't fit in a single model call. They're too large, too detailed, and too information-dense for one inference pass to handle well. So you tile it. You divide the image into a
